How to Play
Zipline
Zipline asks you to trace a single continuous path that visits every square on the board exactly once, passing through a series of numbered stops in order along the way.
Rules
- Draw one continuous line, moving between squares that share an edge (no diagonal moves).
- The line must visit every square on the board exactly once. No square may be skipped, and none may be visited twice.
- The numbered stops must be visited in increasing order as the line passes through them.
- Drag from square to square to draw the path; drag back over a square to erase back to that point.
Tips & Strategy
- Plan the route between consecutive numbered stops first. The path between stop 2 and stop 3, for example, is often heavily restricted by what's around it.
- A square with only one open neighbor left (other than where the path just came from) forces the path's next move.
- Watch for squares that would be completely cut off from the rest of the board by a tempting shortcut. That's usually a sign the shortcut is wrong.
- Deal with corners and dead-end pockets of the board early. Those squares can be reached in the fewest ways, so it pays to secure them first.
Frequently Asked Questions
- Can the path move diagonally?
- No, only straight moves between squares that share an edge (up, down, left, or right) are allowed.
- Does the path really need to cover every square?
- Yes. The path must visit every single square on the board exactly once, not just connect the numbered stops.
- What happens if I draw the numbered stops out of order?
- It won't count as solved. The path must reach the numbered stops in increasing numerical order as it runs through the board.
